1.3 Construction
1.3.1 Housing
The teleph ne type ExResistTel IP2 has a n n c l ured h using made f an
electr static c nductive pressed basic material and a stainless steel keypad.
Opti nally the h using can be c l ured with an electr static c nductive c l ur.
In the fr nt plate f the keypad is a display cut- ut cl sed with a viewing glass.
The h using c nsists f a b x-shaped b tt m part with a tray f r inserting the
electr nic and a curved t p c ver with a keypad.
The t p c ver will be pressed with f ur screws t the upper part with in between a
rev lving seal and generates the intrinsically safe as well as the n n-intrinsically safe
terminal c mpartment. In the tray is a gr uting cup with the embedded electr nic.
1.3.2 Configuration Plug Connector
A 6 pin plug c nnect r sticks ut f the gr uting tray inside the teleph ne (14).
The c nfigurati n plug c nnect r will be used by the manufacturer f the teleph ne
type ExResistTel IP2 f r c nfigurati n nly and must n t be c nnected.
The pr gramming by the installer is n t all wed.
1.3.3 Intrinsically Safe Keypad Connection
An intrinsically safe 14-terminal ribb n cable with a female plug will be carried ut f
the gr uting tray inside the teleph ne.
The female plug has t be plugged t the 14 pin plug c nnect r in the upper part f
the h using securely, bef re the teleph ne will be screwed d wn.

2Commissioning
F r perati n and c mmissi ning, the applicati n f standard IEEE 802.3 is
c mpuls ry.
The ExResistTel IP2 teleph ne must be c nnected t a LAN (L cal Area Netw rk)
c nnecti n. The teleph ne can be p wered with P E (P wer ver Ethernet). In this
case the p wer supply must use the free cable pairs. Using the phant m p wer
supply is n t p ssible and n t all wed.
Alternatively the teleph ne c nnected with an external DC p wer supply (19.2 V –
52.8 V, 12.95 W).
2.1 Mounting
The teleph ne must be installed n a plane surface in vertical perating p siti n
nly. L sen the c ver screws and detach the upper part f the teleph ne (1). If the
pti nal access ry headset is being empl yed, attach the bracket using tw screws
t the rear panel f the l wer part f the teleph ne. (With the access ries named
bef re, the bracket and screws are in the sc pe f delivery. With all access ries a
cable gland is delivered.) Put f ur screws, having a head diameter f 10 t 13 mm
int the h les (20) and attach the l wer part f the teleph ne (3) t the wall r t a
h lder.
Guide the teleph ne wire thr ugh the cable screw cap (4) and place it n the
terminals. Only wires having a sheath diameter f 5.5 t 13 mm sh uld be used
because therwise the IP66 h using pr tecti n standard is n t guaranteed.
Pri r t assembly, check c ver seal f r tightness. Using the plug c nnect r (7), plug
the ribb n cable nt the pin c ntact strip (8) in the upper part f the h using.
Attach the upper part f the teleph ne and fasten it t the l wer part f the
teleph ne with the f ur c ver screws (2). Up n disassembly f pti nal access ries,
suited sealing plugs must be used t cl se the resulting penings.
In this teleph ne c nnected c rds may have hazard us v ltages.
T ensure that n water gets int the encl sure it is essential that n gaskets are
damaged during installati n. The ingress f water can cause accessible parts f the
teleph ne t bec me live.
F r m unting f the cable screw caps nly dedicated t ys are all wed.
The cable screw caps are useful f r fixed m unted cables nly.
